The motor employs carbon brushes which are con -sumable parts. When they
become worn to or near “wear limit”, it could result in motor trouble. When an auto-
stop carbon brush is equipped, the motor will stop automatically. At that time,
replace both carbon brushes with new ones which have the same carbon brush Nos,
shown in the figure.
In addition, always keep carbon brushes clean and ensure that they slide freely
within the brush holders.
Replacement steps.
The carbon brush can be removed by removing the cap cover, cap rubber and brush
cap in that order at the interior.
Due to hammer’s continuing program of research and development, the specifications
